Winter gritting involves spreading a de-icing agent (usually salt) on to roads when forst, ice or snow may make then dangerously slippery. This paper compares two approaches to the problem of managing this operation efficiently: a normative approach and a prescriptive approach. It concludes that a simple measure of routeing efficiency may be misleading when applied to specific situations.
